The LMR3650x is the industry smallest 65-V, 150-mA, 100-mA synchronous step-down DC/DC converter in 4-mm 2 HotRod package. This easy-to-use converter can handle input voltage transients up to 70 V, provide excellent EMI performance and supports fixed, 3.3 V, 5 V and other adjustable output voltages.

The LMR3650x uses the peak current mode control architecture with internal compensation to maintain stable operation with minimal output capacitance. The LMR3650x with the right resistor selection from the RT pin to ground can be externally programmed to any desired switching frequency of operation over a wide range from 200 kHz to 2.2 MHz. The precision EN/UVLO feature allows precise control of the device during the start-up and shutdown. The PGOOD flag, with built-in glitch filter and delayed release, offers a true indication of the system status, eliminating the requirement for an external voltage supervisor. The compact solution size and rich feature set of LMR3650x simplifies implementation for a wide range of industrial applications.
